Antoine Walker (born August 12, 1976 in Chicago, Illinois, was obtained by the Dallas Mavericks along with Tony Delk from the Boston Celtics on October 20, 2003, in exchange for Jiri Welsch, Raef LaFrentz, Chris Mills and a first round draft choice.

Walker attended the University of Kentucky where, as s sophomore, he helped lead the Wildcats to the NCAA Championship. He was named first team All-Southeastern Conference with averages of 15.2 points and 8.4 rebounds in 27.0 minutes and was selected as Most Valuable Player of the Southeastern Conference Tournament.

Drafted by the Boston in the first round (6th overall) of the 1996 NBA draft, the 6'8 forward would go on to spend the first seven seasons of his NBA career with the Celtics. In his rookie campaign he led the team with a 17.5 ppg average while playing in all 82 of the team's games and was selected to the NBA's All-Rookie First Team.

He was selected to his first NBA All-Star team in his second season as he recorded a career-high in rebounding with a 10.2 rpg average. Walker proved himself a dominating scoring force through the next several seasons and was twice more (2001-2002, 2002-2003) selected to the All-Star team.

Just prior to the 2003-2004 season, Walker was dealt to the Mavericks. He started all 82 games, starting each one, for Dallas that season and averaged 14.0 points (the lowest of his career up to that point), 8.3 rebounds and 4.5 assists in 34.6 minutes. He led the Mavs in scoring ten times that season and recorded 27 double-doubles and two triple-doubles, coincidentally in back-to-back games (January 12 vs. New York and January 14 vs. Philadelphia). He also recorded a season-high 65 blocked shots.

The following offseason, Walker and Delk were shipped to the Atlanta Hawks in return for Jason Terry, Alan Henderson and a first round draft pick. He only appeared in 53 games with Atlanta before being dealt back to Boston where he started his NBA career. He played in 24 games with the Celtics and, despite posting good numbers, was traded to Miami in the offseason as part of a 5-team/13-player transaction.

The final three seasons of Walker's career were spent with the Heat where is scoring average fell each year from 12.2 to 8.5 and finally 8.0.

Over the last couple of years Walker has had numerous legal and financial problems and played for the Idaho Stampede of the NBA D-League for two seasons after his NBA career. He is currently a basketball analyst for 120 Sports, a digital sports network and coaches in the Nike Summer Basketball Chi-league in Chicago.
